Non return valves stop water from flowing backwards through the system during times of floor or high water. We also stock rodent barriers to stop rats or other rodents from entering the system.

The backwater valve also referred to as a non-return valve comes with free hanging vertical backwater flaps. These flaps make sure that a building's wastewater flows freely through the valve while simultaneously preventing any backwater from backing up into the building.

What is the Difference Between Check Valves and a Non-Return Valve?

A check valve is a certain type of valve which could prevent back flow from occurring. The check valve needs to be tested and meet very strict standards, which ensures fluids aren't able to be siphoned back into drinking water systems. A Non-return valve is similar in design to a check valve but will not be able to meet the strict criteria of a single check valve.Non-return valves work with a 'swing' - a weighted flap that's held open as long as water is flowing through it. If the water stops, the weight of the flap closes the valve. On the other hand, check valves have an internal obturator - an internal moving element that is held open by the flow of water. If this flow stops, this internal spring mechanism inside the check valve sits back against the valve seat - completely sealing off any back flow.It's worth noting that some companies and suppliers use the term check valve and non-return value interchangeably - so be careful to make sure you're ordering the correct component.
